Put.
Specifically, Fig. 1 to Fig. 3 is referred to, input can be cached using two 40 register reg0, reg1 first
40 data data_in [39:0], according to JESD204B protocol requirements, K28.5 yards is sent always in starting stage transmitting terminal
(i.e. comma detection codes), thus receiving terminal receive at least exist in 40 data of dislocation 1 it is complete by two continuous poles
Property opposite K28.5 composition 20 comma yards (00111110101100000101 or 11000001010011111010).Comma
Then detection from reg1 registers as shown in Fig. 2 take out 40 data found by the displacement comma of ten times is detected
Comma yards of position, and produce the comma code position information sel [9 of ten:0], example as shown in Figure 1, only need to shift two
It is secondary both to have found comma code positions (according to Fig. 2 displacement detections), so the sel [9 for producing:0]=10 ' b0000_0001_00.
Fig. 3 is referred to, state locking module is to produce displacement address according to state machine after comma code position signals are detected
shiftaddr[9:0], to carry out shifting function to all data in subsequent process, its operation is as follows：Enter after reset
SEARCH state, uses intermediate variable sel_tmp [9 in this condition:0] sel [9 is preserved:0] information.When trigger signals have
(comma yards is detected during effect), jump to LOCK states, now sel_tmp [9:0] by shiftaddr [9:0] be given.Institute
Only to need sel_tmp [9:0] it is assigned to shiftaddr [9:0] can both realize locking sel [9:0].Search error letter in Fig. 1
Number output from receiving terminal JESD204B controllers, shows not detecting comma yards when its is effective, now needs to enter again
Row comma is detected, so state machine redirects SEARCH state.Displacement output module is according to shiftaddr [9:0] signal comes right
80 data are shifted, and (80 digits are set to shift_data_reg [79:0]), so that the signal of output word alignment.Such as Fig. 1 institutes
The example for showing, the position signalling shiftaddr [9 of comma has been obtained according to Fig. 2, Fig. 3:0]=10 ' b0000_0001_00,
Shiftaddr [2]=1 ' b1 represents shift_data_reg [79:0] shift_data_reg [41 is taken out:2] after being alignd
40 data.Similarly, if shiftaddr [9:0]=10 ' b0000_0100_00 is then from shift_data_reg [79:0] take
Go out shift_data_reg [43:4] 40 data after being alignd.
Beneficial effects of the present invention are：
The present invention, can be first from register in the data of the presence dislocation of caching when comma detection is carried out and word aligns
Detect the positional information of comma detection code.May then pass through the positional information and determine corresponding displacement address, and then
Word alignment can be carried out according to the displacement address.Further, the application can carry out comma in 40 parallel data
Detection, so the solution of the present invention only need to meet timing requirements under the clock zone of 312.5Mhz (12.5G/40).
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment to be described in detail the present invention, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
